Ireland expected to sign up to first comprehensive climate change deal

Ireland is among more than 160 countries expected to sign up to the world’s first comprehensive deal to tackle climate change at a ceremony in New York later. The Paris Agreement was secured at United Nations talks in the French capital in December. Under the deal the rise in global temperatures is limited to well below two degrees. The changes are due to commence in 2020 but could begin as early as the end of this year.
